Add 4 SuperSpeed USB 3.0 ports to a computer through a PCI slot. The PCIUSB3S4 4-Port PCI to USB 3.0 Card enables legacy PCI slots to support the SuperSpeed USB 3.0 standard, which is capable of data transfer rates up to 5 Gbps. Using USB 3.0 devices with this card will increase data transfer rates with up to 1.3 Gbps of available bandwidth (PCI bus limit) - more than doubling performance compared to a USB 2.0 connection.
This versatile USB 3.0 adapter includes an optional SATA power connector which allows each USB port to deliver up to 900mA of power to connected USB 3.0 devices - suitable for even the most power hungry devices.
A perfect solution for older PCI-based systems or computers with only PCI expansion slots remaining, the card allows those systems to stay relevant and up-to-date with the latest USB technology. The card is also backward compatible with USB 2.0 and 1.x devices, so it will not only work with any future USB 3.0 devices, but will also support older devices.
The PCIUSB3S4 4-Port PCI USB 3.0 Card is backed by StarTech.com lifetime warranty and free lifetime technical support.

StarTech PCIUSB3S4 Reviews
Added USB 3.0 To My 13-Year-Old PC!
I bought to add USB 3.0 to my old Gateway LX6810-01 which I bought new in 2009 and still use as a primary machine. It is stock except for an upgraded Corsair 750W power supply and Sandisk 1 TB SSD. That leaves it with an available PCI slot, which this card fit. However, the case interfered ever so slightly with the USB ports but with some persistence, I was able to plug a USB cable into each port. Also, I received Error Code 31 in Device Manager which meant the drivers were loaded but due to the enabled Windows 10 Fast Startup, it took me some time and internet searching to find out I just needed to perform a restart to make it work. That did the trick. It otherwise works beautifully and I was able to take full advantage of the new 802.11ax standard with a just-released USB Wi-Fi 6 adapter and my ISP's Wi-Fi 6 gateway.
No Linux drivers and does not work in Ubuntu
The driver disc which came in the box only has Windows drivers on it. When I booted up Ubuntu 16.04 with this card installed, Ubuntu does not find the card, nor is it able to automatically install drivers. On the other hand, PCI Express USB 3.0 cards based on the same Renesas NEC D720201 chipset work automatically. The issue is probably related to the onboard PCIe-to-PCI bridge chip on this card. Startech should provide a driver or other instructions to get this item working with Linux. This card worked fine on my Windows XP installation on the same computer, but I need it to work in both operating systems. I tried both the SATA and mini molex connector for power, but it still didn't function in my Ubuntu 16.04 LTS system. This item is way expensive for not supporting Linux. Ubuntu has become rather popular in the last 10 years and it would be nice for more expansion card manufacturers to get on board with more than just Windows support. As a side note, it would be better if the USB ports were rotated 90 degrees. It is a little tricky to plug the USB cable in with the chassis slot being as narrow as it is.
